Ask HN: What are you working on? (February 2026)

I've been building Openfuse (https://openfuse.io), a centralized circuit breaker platform.

Started building it about a year ago after dealing with the same problem across multiple companies: circuit breakers scattered across dozens of services, each configured slightly differently, no single place to see what's happening when things go sideways. The existing options are either libraries you embed in every service (Resilience4j, opossum, etc.) leaving every server stateful, or going full service mesh which is overkill for most teams.

Openfuse gives you a central control plane for circuit breaker policies across your stack. You define your reliability rules in one place, get visibility into breaker states, and can react without redeploying anything.

Been a great project and I'm genuinely happy with where it landed. If you're running microservices or an integration-heavy monolith and have ever cursed at a cascading failure, I'd love to hear how you're handling it today! :)

Building ShotOn (https://shoton.app/) – make your photo share ready in a few clicks without downloading another app.

It basically is a client side web app that adds "shot on" watermarks / photo frames with camera metadata from EXIF data. Also have film simulations like filters to elevate you photo.

Started with just upload + edit, recently trying to add camera mode (think Daze app but in browser). But already hitting some issues when rendering Canvas on live camera feed, might explore WebGL to get real-time filtering working smoothly.

Working on LearnMathsToday – think Duolingo but for maths. It's an AI-powered app that marks your handwritten solutions step-by-step (not just the final answer), so students actually learn the process.

We're focused on Singapore's O-Level maths curriculum right now, with adaptive learning paths and photo-based problem solving. Also running a YouTube channel with free lessons that's crossed 150K views.

The goal is to make structured, curriculum-aligned maths practice as habit-forming and accessible as Duolingo made language learning.

Working on laconic, a "Ralph loop for Research"

API costs for LLM are getting ridiculous. By managing a 4K context window, I can get tiny local models to do advanced research tasks that require dozens of searches and building a knowledge graph for $0.
